SAMUEL BOORN, OF LOWELL, MASSACHUSETTS.

Letters Patent N 101,817, dated April 12, 1870.

'Ihe Schedule referred to in these Letters Patent and making part of the same.

fhall'persons to whorn these presents may come.-

Be it known that I, SAMUEL Boonn, of Lowell, of the countyof Middlesex and State of Massachusetts, havemade a new and useful Invention having reference to Looms for W'eaving Cloth; and I do hereby declare the same to be fully described in the following specification and represented in the accompanying drawings, of which Figure 1 is a-top view, and

Figure 2, a side elevation of the shuttteabox of the lay of a loom, with my invention applied to such box and lay. This invention has for its object the arresting or partially stopping the shuttle before it may strike the picker, the same being to prevent injurious indenting of the picker by the shuttle. This mechanism is not intended to dispense with the usual shuttle-binder to act against the side of the shuttle, as my said additional mechanism is to operate against the nose or pointed part of the shuttle.

In thedrawings- A denotes that part of the lay over which the shuttle-box B is situated.

' O exhibits the picker;

D, the shuttle; and

runs or slides.

In advance of the picker, when in its rearmo'st position,there is applied to the inner surface of one side, 0,;of the shuttle-box, a stationary tapering projection,

: abutment, or buffer, ,G,..haying its inner surface cush toned;

- j Opposite to this-buffer is another buffer, H, which is fastened to a movable arm, I, which, at or near oneend is attached to the outer end or part c of the shuttle-box, so as to be capable of being moved horizontally toward or away from the abutment G. g The arm I is .forced towardthe said abutment G by -means of a strong spring, K, projected from the lay, the whole being arranged substantially as represented in the drawings.

On the shuttle being driven into the box, the advancing nose of such shuttle will be caught between .and by the stationaryand movable buflers, the said picker is supported and claim such; it consisting "inapplying an elastic jaw to the shuttle-binder, to operate it and co-operate with another spring jaw, disposed within the rear part of the shuttle-box; nor do I claim the employment of a stationary stop and a single long bow spring in the side of the shuttle-box, such being to arrest a shuttle during its flight into such box; nor do I claim the employment of springs forsuch purpose.

.Itobbinss invention is to stop the sh little-driver or picker-staff, and act as a spring to the binder. It only acts through the binder to effect stoppage of the shut tle before the picker; whereas, the stationary bufler and the elastic presser, as arranged and used by me, with reference to the picker and the shuttle, operates to check the shuttle only, in its movement up to the picker.

Furthermore, my elastic press'er is pivoted tothe shuttle-box at its rear end,'and the spring is disposed on and screwed to the outside of the box, and is separate from the arm I. This arrangement enables the screws of the spring to betightened or loosened, or the spring to be wedged, as occasion may require, to modify or adjust its presser on the arm I,'as may be requisite from time to time.

I therefore claim the arm I, the jaws G H, and the spring K, as arranged, together and with theshuttIebox, as described, the jaws being in advance of the picker when at its rearmost position in the box, and

the whole being to operate as specified.
